TableView calculates wrong height for dynamic width&height label












2















I've read multiple threads about this but I've found no solution yet.



I'm making a chat-like application





The app has a TableView that has dynamic height cells in it.



A cell consists of a view and a multiline label in it.



If the label has more characters than >250 it gets shortened with an ending "... see more"





Now the problem is that sometimes the label gets cut off.



I played a little with the Line Break setting of the label, and after changing it to Character Wrap the label shows its full text.



Left picture: Character Wrap - - - Right picture: Word Wrap (I need this)



enter image description hereAs you see on the right picture, the "Bt... See More" gets cut off..





I realised that if I set the label's width or the view's width to a fixed size then the problem gets solved: So maybe the problem's root is in the bubble view's leading constraint:



Align leading to Superview
Constant: 0
Priority: 1000
Multiplier: 0.25


(This is needed so that the bubble view expands maximum to 75% of the superview)



I made a GitHub repo for this:



https://github.com/krptia/chatBubbleTest



Help please!





Anyone?

    i suggest you to use manual calculation for best performance or you can use hight caching mechanism which give you average performance

    What happens if you fix the width? Currently they have variable width. Set it to a fixed width just to try.

SOLUTION



I figured out that if I set the bubble view's leading constant the following:



Align leading to Superview
Constant: 0
Priority: 1000
Multiplier: 0.25


In order to set the maximum width to 75%, the label inside wraps incorrectly.



SO I deletet the leading constraint and instead of that I maximize the width via aspect-ratio!



If I use aspect-ratio 2:3



Then I achieve the same outcome, but with the label wrapping correctly!!



Yay



SOLUTION 2.0



Okay, now I have figured out that the bubble view's leading constraint's second item (SuperView.Trailing) was Relative to Margin



After unchecking it, the problem gets fixed, so I don't have to use aspect ratio! Yay



BUT PAY ATTENTION



Because using Line Break: Word Wrap also causes some problems.



Sometimes it tries to break the text into a new line (minimum 2 words) but if the cell was reused then the app might calculate wrong height for the view.

Maybe this issue can be fixed with layoutIfNeeded() or i don't know. Clip is fine for me
